About our new build mastic in Cliffs End
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you are dealing with messy sealant that spoils new finishes and cracked sealant around new window and door frames, we can put it right, on windows & doors, skirting & floors and show homes alike.
In a village or hamlet like Cliffs End, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Each job carries a 12-month guarantee, large or small.

Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around Cliffs End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Your questions about new build mastic in Cliffs End
Will you come out to Cliffs End?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Thanet Parkway station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Are you insured?
Yes. We are fully insured.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. For a village or hamlet like Cliffs End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

What else we do in Cliffs End
Keeping the joints in good condition
After the cure time, these simple habits help:
- Follow the cure time we give you
- Don’t wait for the house to settle if water is getting through
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What we are called out for in Cliffs End
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
It’s worth asking for a quote if you see:
- Plot mastic for developers ahead of handover
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Worktop and upstand sealant coming away
If you’ve bought a new home near Thanet Parkway station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Whether they seal over old material or remove it
- How much experience the applicator has
- Which colour the sealant will be
- How long to leave it before use
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the job changes by surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
New build mastic in Cliffs End: local notes
Cliffs End is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
